Singer Sheryl Crow is auctioning off items from her closet to help raise funds for a leading cancer charity.

The All I Wanna Do star, who is a 10-year breast cancer survivor, is marking Breast Cancer Awareness Month (Oct16) with a massive clean out.

Sheryl has teamed up with eBay For Charity to auction off more than 100 fashion items from her closet, with 100 per cent of the proceeds benefiting Stand Up To Cancer.

The eBay for Charity Sheryl Crow Fashion Auction launched on Monday (03Oct16), and features the singer's stylish dresses, skirts, blouses, pants and hats.

The items are up for grabs until 13 October (16), when each one will go to the highest bidder.

Founded in 2008, Stand Up To Cancer has pledged more than $370 million (GBP288 million) to accelerate the pace of groundbreaking cancer research.

Crow had a similar clear out two years ago (14), when she donated designer shoes, handbags and hats to a charity auction to benefit the Feeding America organisation.

She linked up with eBay bosses for that auction too.

At the time, she explained, "After having volunteered in Nashville, you see the kind of people who come into the food bank. It's not just homeless people, it's moms who are struggling to feed their kids; it's people who are out of work. It's a really necessary entity for a lot of people who are just trying to make ends meet."

Among the items she sold off were a pair of black leather Prada boots, an alligator-embossed leather Coach bag, a pair of Ralph Lauren gardening boots, and a black and white Fendi bag.

"It makes you feel so grateful to have what you have and to be able to help someone else," she added. "The feeling that I get from that is much bigger than anything else that I could experience."
